标题:Process for the synthesis of isocyanates and of isocyanate derivatives

摘要:The present invention relates to a process for the synthesis of isocyanates and of isocyanate derivatives. Isocyanates are obtained by reacting an organic halide with a metal cyanate in an organic medium in the presence of a catalyst consisting of a complex of nickel with at least one organic ligand, in which complex the nickel is in the zero oxidation state. A carbamate or a urea, respectively, are obtained by a subsequent reaction with a hydroxy compound or a primary or secondary amine. Isocyanates and their derivatives are used especially either as refined synthesis agents for the production of pesticides and medications, or as monomers or comonomers for the preparation of many macromolecular compounds.

权利人:UNIV DORTMUND TECH
摘要:A method for the synthesis of a chimeric conjugate molecule by micellar catalysis that may form part of DNA-encoded compound libraries. A DNA-coupled organic starter molecule may be reacted with another organic compound, using a catalyst located within a micelle, to form a conjugate of an organic candidate compound coupled to a DNA identifier tag.

标 题 :Methods utilizing aryl thioimines in synthesis of erythromycin derivatives
发明人：LUKIN KIRILL A
权利人:ABBOTT LAB
摘要:An efficient deoximation technique for use in synthesis of erythromycin derivatives, involving aryl thioimine intermediates is disclosed. The aryl thioimine intermediates can be utilized in a method for protecting a ketone of a ketone-containing erythromycin derivative as a thioimine; a method for deoximating an oxime-containing erythromycin derivative, or a method for preparing a 6-O-alkyl erythromycin derivative. Presently preferred erythromycin derivatives have a C-9 oxime or a C-9 ketone.
